Missing a survey monument breaks the reference framework your measurements rely on. The best course is to establish a new monument to reestablish the control point, with thorough documentation that ties the new marker to the original survey network. This creates a verifiable and recoverable reference for future work, preserving the accuracy and legal record of the survey. In practice, you would search for the original location using field notes, offsets, and nearby markers; if the exact point is recoverable, place the new monument there and reoccupy the lines to reestablish ties. If the original spot cannot be recovered, install a new monument at a position that preserves the network’s geometry as closely as possible, and update the records accordingly. This approach maintains measurement integrity and allows the survey to proceed with a solid, documented reference. Choosing to stop the survey, estimate the position, or approximate the monument would undermine accuracy and the reliability of the results.
